Page 431 - to advise the Senate as to what action, if any, has been taken ... to cause careful soundings to be made between San Francisco, Cal., and Honolulu . . . for the purpose of determining the practicability of laying a telegraphic cable between those two points, or between any point on the Pacific coast and the Kingdom of the Hawaiian Islands," I inclose herewith a communication from the Secretary of the Navy, dated January 30, 1892.
Page 482 - The former and present function of the ocean in the history of the earth and in its economy has forged bonds of kinship between oceanography and many other branches of science. Ever since the ocean became the world-encompassing highway of communication, its surface aspects, embracing the movements of the waters in waves, tides, and currents, have been subjects of observation. With the advance of the physical sciences and a knowledge of the extent of the ocean came the realization...

For if the spacing of soundings be such as to give indication of the presence of the slenderest form that could stand, then evidence of the presence of any orographical forms that may exist is likely to be afforded. Theoretically, the shape of an isolated submarine peak would be that of a solid of revolution in which the resistance to crushing of any horizontal section is equal to the combined weight of the portion of the formation above that section and...

The mammal regulates the PH of the blood through the action of the respiratory center. The sea regulates the PH of its surface-water most probably through the action of seaweed.

The characteristics of this system of circulation may be interpreted by profiles showing the distribution of temperature in the depths and confirmed...
Page 428 - SLIPPED OFF. the sinker to pass swiftly to the bottom. While the apparatus for sounding the sea consisted of a weight secured to the end of a hempen cord which was paid out from a simple reel on the deck of a vessel, no reliability could be attained in the measurement of depths, because the cord employed was necessarily so large as to "become a controlling element in the weight of the system. But •when the project for the Atlantic telegraph cable made it necessary to obtain accurate measurements...
Page 426 - ... took place many feet below the surface, echo was silent, and no answer was received from the bottom. Ericsson and others constructed deepsea leads having a column of air in them, which, by compression, would show the aqueous pressure to which they might be subjected. This was found to answer well for ordinary purposes, but in the depths of " blue water," where the pressure would be equal to several hundred atmospheres, the trial was more than this instrument could stand.
